E. coli terminators

There are several E. coli transcriptional terminators available via the Registry. The most commonly used type of terminator is a forward terminator. When placed downstream of a genetic part that is usually transcribed, a forward transcriptional terminator will cause transcription to abort. However, in general, most transcriptional terminators will not terminate transcription with 100% efficiency. Some RNA polymerases will continue transcribing "through" a transcriptional terminator.

There are also bidirectional transcriptional terminators. Such terminators will usually cause transcription to terminate on both the forward and reverse strand. Again, however, the efficiency of transcriptional termination is not 100% and will often differ in the forward and reverse direction.

Finally, there are also reverse transcriptional terminators that terminate transcription on the reverse strand only.
